DRAFT-EQ UALIZER.

SPECIFICATION forming part of Letters Patent No. 359,065, dated March 8, 1.887.

Application filed September 30, 1886. Serial No. 214,961.

To all whom it may concern:

Be it known that we, MILLARD N. DRAKE and WILLIAM B. DRAKE, of Hanover, in the county of Jackson and State of Michigan, have invented new and useful Improvements in Equalizers; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing, which form a part of this specification.

This invention relates to certain new and useful improvementsin three-horse equalizers.

We are aware that there have been a large number of devices patented and in use for the same purpose, but in all that have ever come Within our knowledge we have found a difficulty in counteracting fully the side draft or in equalizing the draft so as to neutralize the evils arising from said side draft.

The object of the present invention is to remedy this defect and so construct an equalizer that, should the side draft be on either side of the tongue, the device may be so adjusted as to neutralize all evil effects arising therefrom.

The invention consists in the peculiar construction and combination of the parts, as more fully hereinafter set forth. 1

In the accompanying drawing, wherein our invention is shown in top plan, A represents the tongue, upon the top of which is pivotally secured the equalizing-bar B by means of a pin passing through the bracket 0, the equalizing-bar, and the tongue, such equalizing-bar being provided with a series of holes, so that the same may be adjusted to the right or left.

D is another bracket having a series of holes in its top which are coincident with a similar series of holes in the tongue, as shown, and be (No model.)

tween this bracket and tongue are 'pivotally secured the wheels or sheaves E E. III the end of the equalizing-bar there is also pivotally secured the wheel or sheave The chain G is secured, as shown, to one end of the equalizing-whiffietree H, and thence passes underneath the bracket D, around the wheel E, and is laid down and secured to the end of the equalizing-bar B at a. Another chain or cord, I, is secured to the opposite end of the bar H, and is led up and around the sheave E, thence downward around the sheave F, and its free end secured to the tongue at or near the point (Z.

By this arrangement of parts we are enabled to secure a perfect equalization of the draft,

and by the adjustment of the parts as hereinbefore described we are able to counteract the effects of equalizing the side draft.

\Vhat we claim as our invention is- 1. In combination, with a pole, A, the equal izing-bar B, adjustable longitudinally, as described, the sheaves E and E, adjustable upon the pole, as described, and the cords or chains G I'and bar H, the parts being arranged and operating substantially as and for the purposes specified.

2. The combination, in an equalizer, of th tongue A, equalizing-bar B, brackets G and D, sheaves E, E, and F, cords or chains G and I, and bar H, the parts being constructed, arranged, and operating substantially as and for the purposes set forth.
